The basic concept of the web hosting

Choice before the first understanding of the relevant web hosting some of the concepts introduced here, be just, do not understand the purpose is to enable users to quickly understand a number of important concepts in this series of articles will do special presentations.

1, servers, web hosting, vps, web space

The server is a computer equipped with a range of web services to provide necessary software. He and we use the computer is not essentially different from, certain services, yet there must be a commercial server, we use good, Pentium 4 machines to do the server is still very common. Of course, has its own dedicated server, cpu motherboard memory, etc., many of which are to ensure the stability of the server, with everyone using the computer may not not be.

web hosting is the adoption of software technology, points to a server to many web site use, each sites have a certain independence. Advantage is the virtual host server, a much lower price, but also to meet the needs of a lot of owners.

VPS hosting high-level than some, called virtual private servers, but also called the virtual independence of the host, etc., and virtual host is used in common software technology into a single physical server into multiple accounts with the server functionality, but it is more than the virtual host high-level, between the account more independent, give more authority, the external look like a stand-alone servers.

Web space is a popular name for, but also known as web space, Jian Zhan and space, which in fact refers to the server hosting the site, including the above-mentioned servers, virtual hosting, VPS. Can be seen as a kind of virtualization argument refers to web pages stored in that place, the physical is the corresponding server hard drive. Because this name for the official, many of the initial contact with the virtual host of people will be too much focus on the size of the space, the fact there are many important factors to consider.

二. Dynamic IP, fixed IP, an independent IP, shared IP
In fact, this corresponds to two pairs of concepts, since they are all that IP, many people are confusing.
Dynamic IP and fixed IP is a relative concept. Dynamic IP refers to Internet access for each dynamically allocated IP, ADSL in general this is the case, and now the server does not use dynamic IP, the basic, if you accidentally hit a dynamic IP, and certainly hit a liar. IP is fixed, a fixed IP, now rooms are generally fiber, are assigned a fixed IP's.

An independent IP and sharing of IP is a corresponding concept. Independent IP is a website or a hosting account with an IP, but generally refers to a server shared IP virtual hosts all the sites that enjoy the use of IP. Taiwan does not have to account for the allocation of separate virtual host IP, the United States in general have an independent host IP, the host for more information on the United States we can refer to: www.idcspy.com (the United States hosts detective). 10000 Network has issued an information that they have to upgrade his virtual hosts, distribution of independent IP, do not know is not achieved.

三. Windows Linux Unix
First, be clear, whether it is space that windows or linux space, actually refers to the operating system is windows server, upload or linux, and what your own computer operating system.

Because the virtual host does not involve the use of the server operating system, so choose what system of virtual hosts, not because you will not use, but rather depends on what you Jianzhan program needs what kind of environment. In general, PHP select linux operating system, ASP ASP.net choose Windows operating system.

四. ASP ASP.net PHP JSP Almighty space

There are many such name for, ASP space, PHP space, space, and so all-powerful. ASP support ASP space refers to the virtual host, PHP refers to support for PHP, while the all-around space refers to multi-lingual support for ASP PHP web hosting. Because of performance problems, do not recommend people to buy all-around space.

五. IIS Apache MySQL MSSQL Access

IIS and Apache are two popular web server, mySQL MSSQL ACCESS are three kinds of databases. ACCESS which is rather special, as long as the virtual host with the FTP upload space can be used, while MySQL MSSQL Database to be involved in construction of the table and so on. Because of this, a lot of novice owners have chosen a combination of ASP ACCESS, which is harmful to the owners. The current situation, the preferred combination is a PHP MySQL and ASP.net MSSQL combinations. If you do not bias the technical team recommended that choose the former.

六. Online

This is of interest to everyone and very easy to confuse the concept.
From the outset that this is not the properties of the virtual host, virtual host settings only affect the site's online, but can not accurately limit the number of sites online. Maximum number of people online and a lot of factors, in addition to other servers, but also, and you use the web site program, characteristics of the visitors.

On-line numbers are for the time period is, and generally refers to 15 minutes, that is, a people to your site, he was gone within 15 minutes, he is credited to your web site's online population.

Do not believe a lot of online sites to show the number of very accurate, as well as other settings if you know how long the calculation of statistics online, then the result of much less Kaopu.

The number of IIS connections and online relationship is complex, IIS connection may limit the number of the largest online, but the number of people online are more likely to be cpu limited. With regard to the number of IIS connectivity issues behind us There is an article devoted to

More accurately reflect the server load is the PV, and hits, this number is more than the online reference value, but still and procedures related to the different procedures to access a page consumes server resources is not the same.
